Could Sidney Cooke be another Marc Dutroux?

For you guys to understand this question, I'm gonna give you guys a basic rundown of the "Dutroux Affair". The Dutroux Affair refers to the criminal case of Marc Dutroux (who was a prolific serial killer and child molester) and the countless errors that Law Enforcement/the Justice System made while investigating it. These errors include:

• After hearing the screams of children in the basement, Law Enforcement chose to ignore it and leave the home. These 2 girls would eventually starve to death in the cold room in which they were held.
• Despite finding a tape that read "Julie and Melissa", Law Enforcement would return the tape to Dutroux and still wouldn't search the home.
• After Dutroux would abduct and rape 5 girls in his home prior to the killings, he would only spend a few years in prison just to be released. This was before 4 girls would die because of him.

These errors (which there were definitely more, but these were all I could think of) combined with the fact that one his accomplices was "Michel Nihoul", it is suspected that Dutroux could've been working for a government-sponsored human trafficking ring.

Later on, I came across the "Martin Allen Case". Martin Allen was a 15 y.o. boy that went missing in 1979 after allegedly being seen with a man who told him "not to try and run" (according to the witness). During the investigation, the Investigator told Martin's Brother that further investigating the case would be risky since "higher powers" were involved. Some individuals acknowledge the possibility of Martin's disappearance being tied to the V.I.P. pedophilia ring that operated at Elm's Guest House.

I was reading up on some possible suspects and one man by the name of "Sidney Cooke" came up. Sidney Cooke was a part of a pedophilia gang called the "Dirty Dozen" that was responsible for murdering 14 y.o. Jason Swift, 7 y.o. Mark Tildesley, 6 y.o. Barry Lewis, and potentially many more (according to witness who said he boasted to killing 15 people). After these crimes were committed, Sidney Cooke was released in 1998 (similarly to how Dutroux was released after molesting and abducted 5 girls). This led to a public outcry and he was later acquitted.

These errors made by Law Enforcement (in the UK) make me wonder if maybe is more behind the crimes of Sidney Cooke. I wonder if he may be connected to these alleged V.I.P. pedophilia rings operating in the UK. What are your thoughts?
